For $30 you could buy a chrome cast that will cast your screen and many other things to your HDMI TV.

For about the same price you could buy an IP camera that will connect to you router and hence your PC screen. Again getting it to your Tv is a problem, many PC's have an HDMI out put these days. Your trinitron may have problems with that.

If it has a scart plug it will have video input on that plug for a wire connection.
